JBL GTO329



The JBL GTO series speakers are the perfect upgrade to your existing speakers. They are designed with a carbon-injected cone material to accurately reproduce music the way the artist originally intended. The three ohm voice coils allow the speaker to operate at an efficient 4 ohms once they are being powered, allowing them to utilize every watt of power your head-unit or 4ohm stable amplifier can produce. These speakers feature a vented magnet with a high thermal-capable voice coil which effectively dissipates heat, ensuring the longevity of your investment. The edge-driven speaker cones allow greater sound levels with the same amount of power. The wide frequency responses that these speakers provide will leave your ears very satisfied when you're listening to your favorite songs. If quality is your goal, the GTO series speakers by JBL have the technologies to make that happen.




The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.

Mega Mids

First off I'm a die hard JL fan, Silverado currently houses XR 6.5 components in each door with a 10 inch w3 to give it a bassline. All speakers are backed by JL slash series amps to give it a very clean sound. I had a very treble Happy center stage and prominent low notes but I was missing the "fullness" to tie it all together. I installed the 3.5 jbl gto's in the center of the dash right below my deck and supplied them with power from my 300\4. Essentially after tuning I had created a 3 way component set, my sound is now incredible. Now when I crank it up it sounds like I have the whole band performing in my cup holders. So far I have no complaints, if your looking for a a set of small speakers to add some mega mid to your system I highly recommend these drivers.

Partial Review - Tweeters Only

I purchased these to change out the Bose "premium" speakers in the dash of my 2014 Altima 3.5SL. These speakers do NOT fit in the corners of the dash. I did this myself and only had so much time to finish this on a Saturday. The factory corner speakers are only tweeters. I thought these JBL speakers had the "pivot" feature that I have seen on other JBL/Infinity speakers, so I tried to twist the tweeter. It dislodged from its mounting and was just hanging by the leads! So I decided to chop off the tweeters and use them by themselves to do an even-swap with the original speakers. So this review is on the tweeters only.

Wow! Clear, accurate highs. So much more open than the Bose. I listen to acoustic guitar and classic rock. SuperTramp "School" is my test song along with Acoustic Alchemy which I have listened to for years. I know these songs, and these tweeters deliver very accurate sound. For what it's worth, I can recommend part of this speaker. I will install one of the complete speakers in the center speaker spot (it is a 9-speaker system so I had to buy an extra pair to get an additional speaker for the center.) I will post another review for that later (when I get time to install it).

Great amp.

JBL is a pace setter when it comes to electronics. From the MS8 sound processor to the JBL Charge and this amp is not an exception. I am just not sure what the gains botton does because the bass sounds clearer and crisper with the gains botton turned all the way down. I am looking to upgrade my sub from a 275 watts rms to a 500. Maybe the botton may come in handy then.
As you adjust the bottons, you will immediately hear the different effects that each adjustment gives making tuning a breeze.
I tuned mine without the use of the CD.
